Abstract: L'invention concerne essentiellement une pile à combustible à haute température ou un ensemble de piles à combustible à haute température. Selon l'invention, le procédé permettant de dégager de la chaleur d'une pile à combustible de ce type va permettre d'améliorer l'efficacité de conversion d'énergie. Il est prévu à cet effet que la chaleur captée (4, 5, 6) serve à préchauffer le combustible (4') d'alimentation et/ou à préchauffer l'oxygène ou le comburant d'alimentation. Un dispositif de séparation de la chaleur permettant d'appliquer ce procédé se caractérise par le fait qu'au moins une surface de chauffe de l'échangeur thermique (11, 12) est raccordée à la conduite d'amenée du gaz (32, 33) à la cathode (3) ou à l'anode (2) de la pile à combustible ou de l'ensemble de piles à combustible (1). Cette surface de chauffe (11, 12) est reliée de son côté à la conduite d'évacuation (34, 35) des effluents gazeux de la cathode et/ou de ceux de l'anode.

Abstract: The present invention is concerned with copolymers from a hydroxy carboxylic acid and a polycarboxylic acid and/or activated derivative thereof, and especially to such copolymers that are environmentally degradable and biosorbable. Moreover, the present invention is concerned with a process for preparing such polymers that results in achieving lower processing temperatures for the polymers along with providing mechanical properties that are comparable to biosorbable polyesters previously suggested. The reduced processing temperatures make it possible to melt blend heat-sensitive and solvent-sensitive materials with the polymers of the present invention.

Abstract: The invention relates to reprocessing of waste paper in a de-inking process with a flotation downstream of at least one further purification stage. The invention is characterised by the following features:     a) the flotation (32) takes place in a plurality of stages; b1) at the latest after the third flotation stage, the flotation scum (33) accumulated until then is taken off and purified by means of a pressure relief flotation (39) which produces at least clear water (43) and, separately from the latter, the sludge containing the contaminants (46, 48), whereupon the sludge - if appropriate after further thickening - is discharged from the paper treatment process, or b2) first the coarse contaminants and then the fibres are separated from the sludge (33) of the flotation stages - except the last two - in one or two screening devices (36, 37) and the contaminants are at least largely precipitated from the fraction or fractions (38') low in fibres as sludge by pressure relief flotation (39), and the fibre-containing fraction (44) and the clear water (43) from the pressure relief flotation are recycled to a point upstream of the flotation unit (32).   <IMAGE>

Abstract: In scrap shears with a shear stand (1) on which a blade slide (11) is vertically displaceable in guides (8, 9, 34) arranged on the shear stand (1), a first blade (10) carried by the blade slide (11) and a second blade (12) interacting with the first blade (10) and arranged in a fixed position on the shear stand (1), it is to be ensured that scrap drawn into the shearing gap does not lead to deformations on the shears and thus to reduced operability of the same and that the scrap can be removed from the shearing gap with further reduced effort. To this end, the blade slide (11) is arranged according to the invention in such a way as to be movable against the action of elastic elements (22, 37) essentially perpendicularly to the shearing plane while a wider shearing gap is formed. In the event of scrap jamming in the shearing gap, the blade slide (11) can be pulled back despite the action of clamping force, and the scrap can be released solely by this sequence of movement. Preferred embodiments of these shears are provided with preloaded, elastic elements, for example annular-spring elements (22). <IMAGE>

IPC: G02B6/255
Filed: 1993-02-17
Abstract: This invention is directed toward joining, with glass, a waveguide (34) supported by a substrate (26) to an optical fiber (40). In a preferred embodiment, a glass material which melts at a temperature that is lower than the temperature to which the waveguide can be safely heated is applied to either the optical fiber (40) and/or the waveguide (34). The glass material is then heated to cause it to connect the optical fiber to the waveguide. A feature of the invention is the presence of heat breaking slots (38) in the substrate (26) upon which the waveguide resides to thermally isolate the end of each waveguide and the underlying substrate from adjacent waveguides and the portions of the substrate which underlie said adjacent waveguides. The heat breaks restrict heat from being conducted along the end of the substrate from one waveguide region to adjacent waveguide regions when heat is being applied to make a connection.

Abstract: This invention provides embodiments of etalons (10, 14, 18, 22) that eliminate or minimize a falloff of relative radiation modulation as a function of wavelength or FOV. A first embodiment employs a dispersive coating, such as a rugate (12a, 12b, 16), to correct for the phase shift across an etalon step. A second embodiment employs a dispersive coating, such as a rugate (20a, 20b, 24), that provides a stepless etalon in which the phase shifts are generated by the coating. It is shown that in a rugate the phase shift on reflection is directly related to the phase of a sinusoidal index of refraction profile within the rugate, while the frequency of the sinusoidal index of refraction profile determines the wavelength at which the phase shift occurs. By changing the phase of the sinusoidal index of refraction variation as the period of the sinusoidal index of refraction variation is changed, a phase shift of incident radiation is produced that is a function of the wavelength of the incident radiation.

Abstract: The present invention relates to a device for spraying a liquid, particularly a liquid fuel in a burner, of a type comprising a rotary head (8) for centrifuging the liquid, driven rotationally by action of a gas, in particular of the combustion air, on blades (14) which are integral with it. The centrifuged liquid escapes from the centrifuging head (8) via a radially external periphery (12) of the latter which is situated upstream of the blades (14) with reference to a direction (13) of blowing of the gas, in a zone of high pressure of the latter, and offset radially in relation to a radially external periphery (47) of the blades (14). In the case of a burner, any propagation of the flame as far as the centrifuging head is avoided, which makes it possible to avoid soiling of the centrifuging head (8), and the choice of the respective diameters of the radially external periphery of the blades and of that of the centrifuging head can be optimised. <IMAGE>

Abstract: In a method for controlling sample introduction in microcolumn separation techniques, more particularly in capillary electrophoresis (CE), where a sample is injected as a sample plug into a sampling device which comprises at least a channel for the electrolyte buffer and a supply and drain channel for the sample. The supply and drain channels discharge into the electolyte channel at respective supply and drain ports. The distance between the supply port and the drain port geometrically defines a sample volume. The injection of the sample plug into the electrolyte channel is accomplished electrokinetically by applying an electric field across the supply and drain channels for a time at least long enough that the sample component having the lowest electrophoretic mobility is contained within the geometrically defined volume. The supply and drain channels each are inclined to the electrolyte channel. Means are provided for electrokinetically injecting the sample into the sample volume. The resistance to flow of the source and drain channels with respect to the electrolyte buffer is at least about 5% lower than the respective resistance to flow of the electrolyte channel.
